This isn't shaping up to be a good day for Citigroup chief Vikram Pandit. Sheila Bair, the chair of the FDIC, is now looking to change up the bank's management team, per today's Wall Street Journal, and has even reached out someone else—Jerry Grundhofer, the former CEO of U.S. Bancorp—to "gauge his interest" in the top job. No word on how likely this scenario is. But if Vikram really unleashed an "obscenity-laced tirade about the FDIC chairman" last fall when Citigroup lost out in its bid to acquire Wachovia—as the Journal recounts—it's safe to say his neighbors got an earful this morning when he picked up the copy of the Journal on his doorstep.
